State legislators want to take the bite out of dogfighting by siccing the law on spectators who have made New York City the heinous sport’s epicenter.

It’s not enough to punish the owners, breeders and trainers who put on the gruesome spectacles where dogs fight to the death, the legislators said.

Authorities want to prosecute the blood-lusting fans, without whom there would be no market for the animal cruelty disguised as competitive sport.

“We will put teeth into the law and go after the spectators as well as the trainers and promoters,” said state Sen. Thomas Morahan (R-New City). “This must be put to a halt.”

Morahan said he was outraged by a story in yesterday’s Post about New York’s underground dogfighting ring and a sleazy Bronx breeding kennel that Humane Society officials say is among the most notorious in the country.

The Rockland County legislator said he was sickened to learn that spectators, who bet on the matches, can only be charged with misdemeanors.

The new legislation would change the law to a felony punishable by two years in jail or a $10,000 fine, and boost penalties against breeders and trainers, who could face up to six years in jail and a $30,000 fine under the stiffer penalties proposed.

Joseph Lentol (D-Brooklyn) is pushing the legislation in the Assembly.

The sport has come under increased scrutiny in the months since NFL quarterback Michael Vick pleaded guilty to federal dogfighting charges.
